Product Overview
Corsair Air Series LED high airflow PC case fans combine efficient, low-noise airflow with striking LED lighting. The blades are custom-molded for optimal airflow, and they're ultra-thin for less noise and turbulence. The sleeved bearing system reduces vibration for quiet operation. The fan blades are translucent, with a frosted texture, so the light from the four LEDs adds a dramatic effect. Air Series AF fan models perform best in unrestricted spaces with at least 3cm of clearance, and they're ideal for mounting at the rear or top of your PC case as exhaust fans for your PC's motherboard and CPU, graphics accelerators, and other components that fill the case with heat. They work equally well as unrestricted intake fans for areas like side panels or bottom intakes.

Features
• Tuned for high-airflow, large volume cooling • Better performance than standard case fans • Translucent, frosted fan blades and Purple LEDs for a dramatic effect • Nine ultra-thin fan blades and a sleeved bearing system for less vibration, noise and turbulence • Custom fan enclosure for ducting air in the right direction with minimal interference.

The modern PC is potentially a mass of heat output and heat production hot spots. With CPUs rated at more than 100W of heat output, single graphics boards carrying similar ratings (and people want to run two!), multiple hard drives the norm, lots of memory and mainboards covered in heatpipes to combat toasty core logic and PWM circuits, a PC appreciably warming up a room when it’s working hard is no joke.

Watercooling for the PC has been around for years in some form or another, for at least as long as Scan have been in business, with basic physics defining why you want to use it. That means for air cooling, to cope with increasing temperature in the heatsink you need to move the air across it faster. That is why thermostatically controlled fans in your PC will turn faster the hotter something gets.

Anybody who has been near their share of computer systems will appreciate that not all systems make the same amount of noise. There are a number of reasons for why this is so. Firstly, a computer makes noise for different reasons. Generally, anything mechanical is going to make noise.

Very quiet, sturdy and purple glows look great.I'm using this as a roof fan in a Corsair 200R case. It is a well made 120mm fan with a power connector suitable for a 3 or 4 pin motherboard connection.
You can get an adapter which means you can power it from a 4 pin molex straight from the power supply but you don't get speed control that way.
Connected to the motherboard and running a i5 4670K and a decent graphics card this fan hardly makes any noise but helps to keep everything quiet.
Overall very pleased with the purple look it adds to my modest looking case.
